sTATEg TONY nunossr, or `Atrusimmun,,NEW Mexico.

. ritrovata," 'Ik y' Be it known that I, TONY P. Rossnfa citizen-of the United States, residing at Albuquerque, in the county of Bernalillo, nState of New Mexico, have invented certain new and useful Improvements in Tricycles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same.

This invention relates to tricycles and the object thereof, is to provide a supplemental seat'having a series of downwardly extending supporting arms, adapted to be detachably connected to the frame of the tricycle, meansy being provided for supporting the feet of the occupant of the supplemental seat, at the rear of the operator.

A further object resides in the Provision of means for rigidly and detachably connecting 'the supplemental seat frame to the tricycle frame. t

Referring to the drawings, forming a part of the application:

Figure 1, is a side elevational view of my improved tricycle.

Fig. 2, is a detail view of the supplemental seat supportingfranie.

Fig. 3 is a detail View of the intermediate sprocket supporting frame member, and

Fig. 4 is'a plan'view of the tricycle.

Referring to the figures of the drawing, the numeral 5 designates the front wheel, which is journaled in the front fork (3, which latter has a fork head 7 pivotally mounted thereon. The rear fork, comprising the rods 8, extends in a horizontal plane at 9, and is then bent in an oblique plane at 10, and the outer ends of the horizontal portions of the said rods 8, are secured to the fork head 7. bv means of bolts or rivets l1. The rear fork rods 8 gradually diverge outwardly and extend rearwardly to form bearings for the shaft 12, carrying the two rear supporting wheels 13, which latter are mounted in the lower ends of the oblique rods 10 of the fork.

An intermediate fraxre is carried by the rear fork and comprises two parallel V- A'ppneatiqn sied november 22, i915, serial-No. 62,799.

shaped, downwardly extending rods 14 andl 15, which like said `forks are constructed 0f 'the usual'metal tubing, `and the upper ends Aof said rods 14fand 15 are bentoutwardly at an angle and flattened as lat 16. .The flat'- ytened portions 16 are apertured at 17' for Ycuringf.same to the horizontal portion 9 of :enlargement's'are apertured at' 18, and form journals for the operating shaft 19, ywhich 1s disposed in the said apertures 18. -A

sprocket 2O ofV vthe'fusual construction is keyed on the rshaft 19 anddisposed centrally thereof, and between thesaid rodsl 14 and 15, comprising the frame, andthe usual op-A erating cranks 21 and pedals 22 are'secured to the shaft 19, by which the tricycle is op'- erated.

A seat 23, comprising the ordinary saddle construction, yis arranged on a seat post 24, which is of the usual construction, having a threaded shank 24', which is adj ustably mounted inthe apertured plate 25, the latter spanning the rear fork rods, and being secured to same by bolts or rivets 26. vA

small rear sprocket 27 is keyed on the rear shaft 12 and revolves therewith, and a chain 28 passes over the sprockets 20 and 27, serving to propel the tricycle when the pedals are actuated. l

Detachably mounted on the rear fork isa tubular supplemental seat frame 28, com-4 prising a seat post rod 29, and the metal tubing comprising the frame intermediate its length, is longitudinally split to form the two outwardly diverging supporting rods 30, the lower ends of which are secured by bolts or rivets 31, to the lower part of the obliquely extending frame rods 10, and the forward or front supporting rods 32, which diverge outwardly and have their ends secured by bolts or rivets 33, to the upper part of the obliquely extending rods 10 of the rear fork.

Foot supports 34A are secured tothe rods of the rear fork by bolts or rivets 35 andare constructed of spring metal, and project outwardly from the fork rods to receive the feet of the occupant of the rear seat.

It is obvious that by the above construction, ,a unitary structure is provided and the same is vpossessed of fewness of parts and simplicity of structure and operation.

The operator of the tricycle, positioned on the front seat, actuates the pedals, thereby driving the front sprocket, and by means of the vchain the rear sprocket, which is 'keyed to the rear shaft 12, is actuated, serving to impart motion to the rearywheels.

From the foregoing description, taken inv lmay be m'ade'when desired as are within the scope of the claim appended hereto.

As will be seen, the supplemental seat frame 28, may be detached from the rear fork by removing the bolts 31 and 33,- and the tricycle used in the ordinary manner, in

which case the machine may be mounted by means of the step rod 36, secured adjacent the Vlower ends of the rods l0 of the rear vfork and spanning same.

Copies of this patent may be obtained for Likewise the supplemental seat 37, may be adjusted on the seat frame 28, in the ordinary manner.

What I claim and desire to secure by Letters Patent, is: l

A tricycle, vcomprising in combination, 'a front fork, a rear fork having its front end pivotally mounted upon the front fork and extending first rearwardly and then downwardly in divergent arms which begin at the pivotal mounting, a comparatively large wheel supporting` the front fork, and comparatively small wheels supporting the rear end of the rear fork, a pair of V-shaped frames suspended side by: side lfrom the arms of the frear `fork across the angular downward bend ofitspathfand 4being' brought-td gether below the latter to provide a. sprocket bearing, a sprocket mountediin saidl bea-ring, a second pair of Veshaped frames rising from the downwardly directed portions of the members of the fork and meetingthereabove to provide a seat support, said. sprocket and seat supports. serving to brace the members of the rea-r fork, seats carried by the rear fork andupon said sea-t support and a driving connection between the sprocket and the rear wheels. Y

In testimony whereof, I aix my signature, in the presenceof two'V witnesses.-
